# Answers to Our 6th Anniversary Instagram Brain Teasers!

Last week, we celebrated six years of PuzzleNation Blog by announcing a week-long puzzly social media blitz.

Facebook and Twitter saw twice-daily alerts for the puzzle of the day for both Daily POP Crosswords and Penny Dell Crosswords App, cuing solvers to contact us with the answers to particular across and down clues.

Instagram solvers were encouraged to tackle a series of brain teasers, and today, we’ve got all the answers for you! Let’s jump right in.

We started off on Tuesday with this relatively straightforward brain teaser: How can you add eight 4s together so that the total adds up to 500?

We got the most responses to this one, and it’s no surprise, as we have some very crafty followers on Instagram. The trick here is number placement. By grouping 4s, you create larger numbers that make it easier to add to your total.

Solution: 444 + 44 + 4 + 4 + 4 = 500

Wednesday’s puzzle involved placing the numbers 1 through 8 into the grid above. Consecutive numbers cannot appear in an adjacent or diagonal box.

This puzzle was actually created and submitted by a PuzzleNationer named Sanjana, so kudos to you, Sanjana, as you made one heck of a brain teaser!

Here’s the solution. (Using the same numbers in reverse or flipped layout creates four different variations on the same solution.)

Thursday’s brain teaser put your Scrabble and Upwords skills to the test, as we played a round of Quad-Doku! The goal is to play each tile, one at a time, onto the board, forming a new common word (or words) each time. Do this with all 8 tiles in any order. By the end, all four corners will have changed.

This is a nice chain-solving puzzle, and here’s the solution we came up with:

F makes FOUR/FIND, S makes FINS/SEEM, A makes SEAM, B makes FIBS, C makes SCAM, W makes SWAM, L makes FOUL/LOOM, and P makes LOOP/SWAP.

On Friday, we posted a riddle to test your puzzly skills. Once I am 24, twice I am 20, three times I am unclean. What am I?

Solution: The answer is X. It’s the 24th letter of the alphabet, two X’s makes 20 in Roman numerals, and three X’s marks something as inappropriate for some viewers.

Monday brought us our final brain teaser, a matchstick puzzle (or, in this case, a toothpick puzzle). Can you move four toothpicks in order to change the zigzag path into 2 squares? The two squares do not have to be equal in size.

In the image above, we’ve circled the four toothpicks to move.

And here is the completed puzzle, with two squares of unequal size.

How did you do, intrepid solvers? Well, based on the responses we received, pretty darn well! We’ll be reaching out to contest winners later this week!

But in the meantime, we’d like to thank everyone who participated in our PN Blog 6th Anniversary event. You help make this the best puzzle community on the planet, and we are forever grateful.

# Six Years of PuzzleNation Blog (Plus a Contest)!

Yes, we’re celebrating today, fellow puzzlers and PuzzleNationers!

We’re celebrating because it is the sixth anniversary of the very first post here on PuzzleNation Blog! Yes, we’ve been on this puzzly journey together since August of 2012, and in my admittedly biased yet humble opinion, it’s been a brilliant one.

In those six years, we’ve published over a thousand posts! (More than nine hundred of them penned by yours truly.) We’ve delved into puzzle history, cracked diabolical brain teasers, marked milestones like the centenary of the crossword, and even rejoiced at puzzly proposals of marriage!

And to celebrate six years of PuzzleNation Blog, we’ve got a week of activities planned for our marvelous readers and fellow puzzlers!

For starters, we’re loading over a hundred new pins to our Pinterest account for your viewing pleasure!

And we’re launching a promotion across all of our social media platforms to celebrate the anniversary. It’s our PuzzleNation 6th Anniversary Contest!

Starting today, and every day for the next five days, we’ll be posting a different brain teaser on Instagram.

Also starting today, keep your eyes peeled on Facebook and Twitter, because each day for the next five days, we’ll be asking for a single answer from that day’s Daily POP Crosswords App puzzle and that day’s Penny Dell Crosswords App puzzle.

(These will be separate from the usual Crossword Clue Challenge posts, and we’ll mark them with “PuzzleNation 6th Anniversary Contest” to distinguish them.)

Message us on FB or Twitter with the answer, or message us on Instagram with the answer to a brain teaser, and you’ll go into a drawing for a terrific prize! (And yes, since there are different brain teasers each day and different answers for each of the two daily puzzles, you can enter multiple times to increase your odds of winning!)

Enjoy the contest, fellow puzzlers. It’s a small thank you for being a part of the PuzzleNation community.
